At the GUT scale we implement the parameters of model 1 and model 2, which are given in Eq. (REF ) and Eq. (REF ), respectively, as described in Section REF . Furthermore, using Eq. (REF ) we determine the dimension 6 operators at the GUT scale. To calculate the RG evolution of the SM parameters we use the Mathematica package REAP [1]}. For the dimension 6 operators, on the other hand, the running is computed explicitly according to Eq. (REF ). For the SM gauge couplings and Yukawa matrices the running is computed at 2-loop, while the running of the right-handed neutrino mass matrix as well as of the effective neutrino mass operator is computed at the 1-loop level.
